located near the center of the island, best bet is to rent a motorcylce to get there, although i'm sure taxi is an option too.
We entered for free somehow but i believe they charge a little to park usually. You can bring your food and drinks inside or buy there. Then over the rackety bridge for walk along a jungle path for about 30meters to get the main waterfall section.
Great place for a picnic, lots of flat rocks, lots of shade, still-water pools aplenty to paddle in, lots of nice photos to be had. Worth the trip#phuquoc #vietnam #waterfall #beachlife #trip
